Vaginal orgasm during intercourse

I'm 42 years old and recently divorced after 19 years of a frustrating marriage where the lack of sex was one of the main causes of divorce. I was only able to get clitorial orgasms and only after long and forced efforts. About 2 months ago I met my current boyfriend, also 42 but with the sexual strength of a 20 year old man, also counting with a good size "tool of love". He can last long periods of time without having an orgasm, which makes our sex life very exciting and different for me. I found out that even though I'm very happy and aroused when together, I can only have clitorial orgasms and he started to question me if he wasn't capable of satisfying me. When I asked why he explained I should be able to have vaginal orgasms during intercourse and not feeling the need to "reach down" myself. I now wonder if I could experience a vaginal orgasm. I never had one. Is there any particular position, exercise or help for me to learn? I have to admit that sometimes I "fake" my orgasms to make him feel satisfied, and I know is wrong, but on the other hand I'm very satisfied even when I don't have an orgasm. I'm just wondering if perhaps I'm missing something that I can teach myself to experience, the vaginal orgasm during intercourse.
Please help me.
Thanks. Curious "S"

Those women, who succeed in reaching orgasm during intercourse, select a position which causes the clitoris to be stimulated during the intercourse. But most women need fondling of the clitoris before intercourse, since it often takes a much longer time for a woman to achieve orgasm, than for a man.

It is also quite common that women stimulate the clitories with their hands during the intercourse, in order to achieve orgasm.
